Hello everyone,
I know there is an open hardware arduino printhead called InkShield. I was just wondering if anyone has had any experience with InkShield before? And I was wondering if it is possible to hack inkjet printheads (Piezoelectric or thermal) in InkShield module?
I want a way to control ink drop injection, out of each printing nozzle.
I do have this honey comb grid/mesh surface. Each hole has a diameter of roughly 0.8mm.
I need to shoot ink droplets into one particular hole at each time. So for example, as you can see from the following picture, at a given time I want to shoot the ink through the Red holes only then at another time I would like to shoot the ink drops to the green holes only and so on.
I was thinking of using a opensource inkjet printhead for this purpose. I was thinking of overlaying printhead nozzels on top of my mesh and send orders to the printhead to activate only some specific nozzels at a given time. But I don’t know how to control printheads like the way I want and I don’t know if that is possible or not? Is it possible to hack a printhead so that you can send commands on which nozzle to be activated or not?
Any recommendation would be appreciated,
thanks
Did you realize that you'll have to position the print head exactly over the holes, in x and y direction?
Eventually you need a separate head for each color.
Activation of a nozzle is simple: you send the nozzle index to the board (3-4 digital outputs), and a pulse to spit out a drop. See the tutorials and examples for the InkShield.
